Pet feeding device and recognition system for pet feeding device

Abstract

The present invention discloses a pet feeding device and a recognition system for pet feeding device, comprising: a housing, a hatch door arranged on the housing, and a food tray arranged in the housing, wherein the food tray can prevent pets from spilling food outside the food tray during eating. The housing is provided with a driving mechanism and a hatch door linkage mechanism, wherein the hatch door linkage mechanism is drivingly connected to an output end of the driving mechanism and connected with the hatch door. The driving mechanism is used for driving the hatch door linkage mechanism to lead the hatch door to open and close. This solution not only controls the food intake of the pets, but also controls the feeding time of the pets.

         2 . The pet feeding device according to  claim 1 , wherein the hatch door linkage mechanism includes a transmission gear set and a transmission rack,
 the transmission rack is slidably arranged within the housing, the transmission gear set is drivingly connected to the output end of the driving mechanism and the transmission rack, an end of the transmission rack is slidably connected to the hatch door.   
     
     
         3 . The pet feeding device according to  claim 2 , wherein the transmission gear set includes a first transmission gear set and a second transmission gear set which are drivingly connected to the driving mechanism;
 the transmission rack includes a first transmission rack and a second transmission rack, and both the first transmission rack and the second transmission rack are slidably connected to the hatch door.   
     
     
         4 . The pet feeding device according to  claim 2 , the first transmission gear set has at least one more gear than the second transmission gear set. 
     
     
         5 . The pet feeding device according to  claim 4 , in the first transmission gear set and the second transmission gear set, the gears directly engaged with the driving mechanism, and the gears directly engaged with the first transmission rack and the second transmission rack share the same transmission ratio. 
     
     
         6 . The pet feeding device according to  claim 3 , wherein sliding connection points of the first transmission rack and the second transmission rack with the hatch door are located on the same horizontal plane. 
     
     
         7 . The pet feeding device according to  claim 3 , wherein a side of the transmission rack is fixed with a transmission inductor, and the transmission inductor communicates with the driving mechanism;
 the transmission rack is provided with a first induction structure and a second induction structure for triggering the transmission inductor; when the first induction structure or the second induction structure triggers the transmission inductor, the driving mechanism stops driving the hatch door linkage mechanism to rotate or drives the hatch door linkage mechanism to reverse.   
     
     
         8 . The pet feeding device according to  claim 7 , both the first sensing structure and the second sensing structure are protrusions arranged on the transmission rack, the transmission inductor is a press-type inductor, when the first induction structure and the second induction structure move to a position where the transmission inductor is pressed, the driving mechanism stops driving the hatch door linkage mechanism to rotate or drives the hatch door linkage mechanism to reverse. 
     
     
         9 . The pet feeding device according to  claim 2 , wherein the hatch door includes a first hatch door and a second hatch door hinged with the first hatch door, and the transmission rack is slidably connected to the second hatch door. 
     
     
         10 . The pet feeding device according to  claim 9 , the second hatch door is foldable relative to the first hatch door. 
     
     
         11 . The pet feeding device according to  claim 10 , an articulated shaft between the first hatch door and the housing is parallel to a horizontal plane, and another articulated shaft between the second hatch door is parallel to the horizontal plane. 
     
     
         12 . The pet feeding device according to  claim 9 , wherein the second hatch door is provided with a sliding groove, and the sliding groove is used for limiting a displacement distance of the transmission rack. 
     
     
         13 . The pet feeding device according to  claim 1 , wherein a food control mechanism is also provided in the housing. 
     
     
         14 .
